FUEL TANK non rononnsnnnrnn LIKEL Application filed- April 5;

A feature of my-"invention is a valve to prevent spilling ofthe' oil in case the tank is tipped too far or in case the tank is filled too. full.

Another feature is the combination of sa d valve with a check valve.

Another feature is the combination of the spilling-prevention valve with'a feed pipe for the tank;

Another feature is a guard more fully described below. v 7

Other features will be pointed out below.

In the drawing Figure 1 is a plan of a tank embodying my invention;

Figure 2 is an elevation of the same,'partly in section;

Figure 3 is an enlarged. detail to prevent spilling; and V i, Figure 4 is an enlarged detail of the check valve. e

Tank A has a suitable'drain plug a and handles a. The cover A may be soldered or otherwise suitably secured in place and is per forated for suitable reception and hold ing of pipe bushings b and b and valve seat member 6 Safety filling pipeB is suitably connected to bushing b and is used as an inlet for the oilor other material 6 and extends nearly to the bottom of the tank to prevent gases from escaping at the filling point. Cap 12* is provided for pipe B.

V B is a suction pipe having a fine mesh strainer b at the bottom, said pipe leading of the valve to joint member 13 which in turn is connected to flexible conduit B "leading, for example, to a vacuum torch such as is shown in my pending application filed January 21,

' 1921, Ser. No. 488858. In the joint member I provide a non-return valve b guided at Z)? and which will be drawn up away from its 1 seat 6 by the vacuum but which will engage Specification of Letters Bate n15. Pgtte tfl,J 3,11, 31,-, 192 2;

its seat to prevent pressure on the tank in case, for example, of an accident to: the burner head,

The valve seat member 6 has a passage (Z and a larger conical passage al and is provided with a bar-d to hold ball (Z from falling out. I also suitably attach to the bottom ofniember 6 a fine mesh wire-screen (Z to act as a flame arresterin case any gas should come out through passages (Z and-1dand become ignited outside of the tank.

E is a flexible conduitto conduct air to the torch, this conduit being preferably con-I nected to joint member E which is connected to the'top of the tank and which in turn IS COHIIQCtGd to flexible conduit E leading to the source of compressed-air. r V lprovlde a guard for the flexible conduits E and B where they join the members E F and B this guard consisting of two upright portions welded to the" cover A? and as these are alike I show only one, namely G, these portions being connected by cross-bar G" the latter being provided at each end with channels 9 and g so that the torch itself may conveniently rest in these channelswhen not in use.

In using my tank the oil other fuel b i will enter by way of pipe B,v;member 6 cooperating with pipe B in this'filling action by permitting escape of air outward through passages (Z and d.

operates with B by permitting the inward passage of airthrough passages d, and d. Member Z2 has another function which is to engage ball (Z in case the tank is tipped over, the result being that the'oil'can not escape because the ball (Z will engage the wall of passage dhnd consequently the danger otfire from the spilling of oil is averted, i

When the oil is to be drawn oil by vacuum action member 6 e0- It will thus be seen that the member 6 has four'functions, namely, permittingthe outward passage jot-air to coo perate with pipe '13 for filling, permitting the inward passage of air to cooperate with pipeBf for drawing 01f, toprevent: spilling ofoil and to provide a fiame'arresteu I What I claim'is: 1

suction conduit; a check valve therein; an opening; normally above the fuel and; leading from the atmosphereso as to cooperate with said conduit; andmeans actingauto- 1'05 1. A tank for liquid fuel comprising a matically to close said opening to prevent escape of the fuel through said opening.

2. A tank for liquid fuel comprising a suction conduit; a checkvalve therein; a con- 'duit leading into the tank for feeding the opening to prevent escape of the fuel through sald opening.

3. A device of the character described 7 comprising a feed conduit ;"a tank; a member to connect said conduit with the tank; and a guard to protect the joint betweensaid conduit and said member, said guard having provision for holding the torch when the latter is not in use.
